The AB Ed promised to eat his hat on camera if it was a technical fault with AB causing this.
The problem, I recall, is with Google- so when people come to AB via a google search and select the topic, google is pointing to the wrong topics in some cases. I was just checking whether this was the explanation in all cases as I would expect that normally only new users would come in via Google search- most regulars such as maeva and me would have it as a favourite. Yet clearly even people like maeva are having problems.
